- Jacaena lunulata
Natural history Types of this new species were collected in evergreen hill forests of Doi Suthep and Doi Inthanon between 1250 and 1750 m.
Diagnosis Males of J. lunulata sp. nov. are similar to those of J. schwendingeri comb. nov. but differ by having a crescent-shaped conductor that is distinctly broader and strongly curved backward (Figures 6 A, 9 D, E), a tegulum that is greatly expanded, and the distal RTA of the male palp that is digitiform (Figure 6 C). In comparison, in J. schwendingeri comb. nov. the conductor is narrower and its sharply pointed apex is abruptly bent (Figure 4 A, C), the tegulum and the distal RTA are significantly smaller. Females can be distinguished by the rather simple internal genitalia, the ID of which consists of circular proximal ducts, the more convoluted ID, and the poorly defined spermathecae (Figure 8 G cf. 8 F).
Etymology The specific epithet is derived from Latin adjective (lunulatus = crescent-shaped), referring to the lamina-shaped conductor on the male palp.
